I To all whom it may concern:

Be it known that I, Tnoiras CoA-rss, a citizen of the United States, residing at Youngstown, in the county of Mahoning and 5 State of Ohio, have invmted new and useful Improvements in Turbine-Mountin for Bo er-Flue Cleaners, of-which the fol owing is a specification. y

This invention relates to that t of boiler iodlue cleaners wherein a driving tur ineis emplo'ed to rotate the cleaning tool or cutter lai drivin turbine being operated byflui pressure. or this type of flue cleaner the present invention'contemplates a novel and of elements which provlde an improved aringfor the turbine or wheel element, and also simple and itive means for adjusting the wear of the aring to ate the play or lose motion.

A lier object of the invention is to protviide a strong and practical cou lin and the cleaning tool or cutter.

I the invention has in view an n *S migrovsment in the structural arran Ynicht an Quilting of the operative parts o a flue cleaner of the turbine type whereb -tlie tool is improved throughout and a t iomuglily effective driving force is secured.

3 With these and many otlieroh'ccts in view, which will readily appear to t ie mechanic as the nature of the invention is better understood, the same consists in thev novel construction, combination and arrangement of 35 parts hereinafter more fully descnbed, illustrated and claimed.

The eential features of the invention involved in the bearin bine and the ad'usta le coupling thereof to 4 the stationary ceding head are necessarily susceptible to structural change without departing from the scope of the invention but a preferred embodiment thereof is shown in the aoco. inpanying drawigfs in which U Fi is an enlarg longitudinal section view of a pressure operated flue cleaner embed i the resent invention. Fig. 2 is a de tail p an view partly in section of the A turbine an the adjacent feeding 5 head s owing the o rative relation of the co-operating artso these elements. Fig. 3 is a cross sec tonal view on the line 33 of 'has suitably mounting of the tui'- ramm inyse, iso?.

Fig. l. Fig. 4 is a similar view on the line 4-4 of Fig. 1, showing in elevation the preferred type of cleaning, tool or cutter employed as a part of the apparatus.

Like references designate corresponding parts inthe several figures of the drawings.

The cleaner embodies in its general organisation a tubular easing l of a size to be convcniently handled in connection with the tube, andis adapted to accommodate there-` in the driving turbine and the parte immediately cooperatin therewith. The casing fitte( to one end thereof a coupling nipple 2 to which is connected the usual pipe or hose for supplying the steam or other motivo agent, under pressure, to operate the driving turbine.

`Within the casing 1 is arranged ra stationary feeding head 3 provided, (in what may be termed the llange or diaphragm portion near the edge thereof next to the inner wall of thel caeinglwith n circular series of oblique tangentially disposed feed ports 4 which serve to deflect the steam or other motive agent in the proper direction against the buckets of the driving turbine 5 to be presently referred to. ln addition to having a inain diaphragm or flange portion ierced by the feed ports 4, the said feeding iead 3 is provided at one side with-a projecting poet extension 6 which is of an interiorly stepped formation to secure proper reinforcement, and is designed to be driven or otherwise rigidly secured within the counter-bored opening 7 of a rigid distributingring 8 arranged within the casing and rigid with the inner wall thereof. This inner distributing ring, by reason of its count-er bored openin 7 registers perfectly with the exterior of t e )ost 6, and said ring ma be either separato lrom or integral with tie casing l, it only being necessary that these parte be rigid so4 that the rin v S will constitute a part ofthe stationary geding head foi' the steam vor other motive agent.

It will be observed in the construction referred to, that the ring 8 is pierced near its periphery with a continuous circular series of e openings 9 vwhich. serve as supply ports for eading an ample supply of steam or inotive agent directly into the feed ports 4 of the ec g head. In this way the steam or nion mais u" 80M l med l 111m im t0 the Vll'- voeive a screw driver or other tool for tuning ous feed ports, thus securing a more effective the bolt to take up wear.
